The reconstruction

A year later, the police staged a reconstruction of the theft, with a stopwatch and extras. It went so well that, at the end, a grenade was missing again. Some clues in this case come as riddles. If one stumps you, a hint will solve it. Eight people and one grenade, one per row and one per column. Almost nothing is said directly: you'll have to cross everything.

Suspects

• Alvarina, the police inspector: She timed the theft at twenty-two minutes, with extras. She hasn't tried it without extras.
• Bruno, the extra playing the thief: He rehearsed for a week. He says he could do it for real now, but doesn't want to.
• Celestina, the extra playing the sentry: She played a sentry who saw nothing. They told her it was very realistic.
• Damião, the corporal who was on base that night: He was there on the real night and came to watch the fake one. He says the fake one has more people.
• Evangelina, the journalist following the case: She has followed the case since day one. She has spent more hours at Tancos than some soldiers.
• Filinto, the stopwatch technician: He has the only stopwatch at the reconstruction. He stopped it twice and never said why.
• Gracinda, a defendant's lawyer: She came to make sure the reconstruction reconstructed nothing. She took notes on everything.
• Heitor, the lorry driver: He played the getaway lorry. He says the real lorry was bigger, and nobody knows how he knows.
